"ritt ne a imown that nwnm r. Marmi, a citizen of the United States, and a resident or the city of Chicago7 in the county ofV Cool;

n and State of illinois, have invented al new and useful improvement in Car-Roofs, of which the following is a specification.

This invention relates to roof sheets for inside, outside, and single-course car roofs,

and particularly to a roof sheet which is composed largely of pulp or ber pressed into the required shape and reinforced with metal around the edges.

rEhe object of the invention is to reduce therst cost and prolong the life of car groots of the type which heretofore have been composed entirely of sheet metal by -combining liber or pul board with the metal portions of thereof s este, and thereby reducing the amount or' sheet metal reqmred .and protecting it from rust;

flhe invention consists in the construction of the roof sheets partly or pressed orv rolled sheets of pulp,'ber, ypsum, or the like, and in the form of the s eets and their :arran ement in the car roofs. .The invention rther consists in the details of the car rooshown in the drawings and hereinafter described. l.

.Further objects of the invention appear connection with the description of the car rooir shown in the drawings, and'what the invention consists in is more particularly dened in the appendedclaims.

ln lthe drawings, wherein the same reference characters designate similar parts in the several views,

Figure 1 is a plan view of a portion of a car roof, partly broken away Ato disclose the construction of the under side of the roof; Fig. 2 is a vertical transverse section through the vrid e portion orA the roof, on

the line 2-2 in ig. 1; (I

Fig. 3 is a plan view of the metal skeleton of a roof'sheet ready for the pulp or ber to be molded in place;

,Fig ,d is a vertical transverse' section through the eaves portionof the roof, on the line Jg-4 in Fig. 1';

Fil 5 isl a vertlcal cross-section` through a car ine and seam or joint'between two roof sheets, on the line 5--5 in Fig. 1; and ii a view similar to Fig. d, showing Eormci? eaves construction,

-@For purpose of illustration, the drawings show the invention applied to a singlecourse roof, that is, a. roof having no sheathingv boards, there being only one layer or course of sheathing material coveringthe roof framework' -but lthe invention can be applied to roofs having sheathing boards in' addition to the roof4 sheets, which' may be arranged either above orbelow the sheathing boards.

In the construction shown in the drawings, the roof framework consists of metal carlines which span the car from one side plate 11 to the other at intervals apart of two to three feet or more, and which support the wood purlins 12 and ridge pole 13.

which run from end to end of the car.

The ropf sheets 14 are arranged in pairs -on opposite sides of the roof, and rest upon the side plates, purlins, and ridge pole. The.

roof sheets are composed of fibrous or light lcementitlous material which can be pressed, rolled or otherwise molded in placeabout a Patenten man. as. aars.

suitable framework 15 of metal. Preferably, 4

/the side edges of the framework'are metal strips, the outer margins of which are anged up and turned in overthe body portion to form side marginal flangesv 16. These side flanges 16 ,hook into the side walls of inverted channel-shape seam covers 17 which 4straddle the flanges of adjacent prooi sheets and the side walls of which have their lower Hat fold or flange 21 which engages with a flat fold or flange 22 on the top e'dge of the -eaves flashing strip 23. `Near the ridge'end i of each roof sheet, at the middle of its under side, is a circular 'boss or projection 24 which fits lnt'o a recess 25 in one 'end of a metal strap 26 which is secured across 'the ridge-for pivotally holding each pair of roof sheets. The under side of the boss 24 is protected by .a sheet metal cup 27, which iesI is molded into 'thematerial of the bodyl of the sheet. Wire mesh 28 or other suitable Wise seenied to the side el the eer. The

ridge ends of the side seein Covers l? and the ends of the dge seein Covers 19 are covered hy edge @einer Caps 3l Whieh sie seouied te the ridge pole by belts.
